Question

Find the loss percent if CP-200,SP-180​

Answer 1

Given :

• Cost price = Rs.200
• Selling price = Rs.180

To Find :

• The Loss percent

Solution :

Loss percent when Cost price (CP) and selling price (SP) is given by ,

$\\ \star \: \boxed{\purple{\sf{Loss\% = \dfrac{(CP-SP)\times 100}{CP}}}}$

We have ,

• CP = Rs. 200
• SP = Rs.180

Substituting the values ,

$\\ : \implies \sf \: loss\% = \frac{(200 - 180) \times 100}{200}$

$\\ : \implies \sf \: loss\% = \frac{20 \times 100}{200}$

$\\ : \implies \sf \: loss\% = \frac{2000}{200}$

$\\ : \implies \sf \: loss\% = \cancel{ \frac{2000}{200} }$

$\\ : \implies {\boxed{\pink{\sf{ \: loss\% = 10\%}}}} \: \bigstar$

$\\ \therefore \underline{\sf{Hence\: ,\:The\: loss\:percent \:is \bold{\:10\%}}}$

Answer 2

cp = 200

sp = 180

Loss% = (Loss)×100/cp

=> Loss% = (sp-cp)×100/cp [ ∵ Loss = cp-sp]

=> loss% = (200-180)× 100/200

=> loss% = 20×100/200

=> loss% = 10%
